lNKlNG DEVICE FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 702,740, dated June 17, 1902.

Application filed December 2, 1899. Serial No. 738,945. (No model.)

To all whom it may concern:

Be it known that I, PETER'F. NILSON, a citizen of the United States, and a resident of Jerome, in the county of Yavapai and Territory of Arizona, have invented certain new and useful Improvements in Inking Devices for Type-Writin g Machines, of which the following is a specification. I

The invention relates to type-writing machines; and its object is to p'rovidea new and improved inking device for directly and properly inking the type immediatelybefore the impression is made on the paper.

The invention consists principally of an inking device mounted to swing in and out of the path of the several type-bars.

The invention also consists of certain parts and details and combinations of'the same, as will be fully described hereinafter and then pointed out in the claims."

Reference is to be'had'tothe accompanying drawings, forming 'a part of this specification, in which similar characters ofreference indi-' cate corresponding parts in'all the figures. Figure 1 is a front elevation of the improvement as applied, parts of the typewriting machine being in-section. Fig. 2 is an end elevation of the same with parts of the machine in section. Fig. 3 is an enlarged side elevation of the improvement with the impression-roller in section.' Fig. 4 is a longitudinal section of the impression-roller, and

Fig. 5 is a cross-section of the same. Fig. 6

is a diagrammatic elevation of the type ac- 3 5 tion.

The type-writing machine on which the improvement is applied may be of any approved construction; but, as shown in the drawings, the machine is similar to the one described in the application for Letters Patent No. 597 ,828, filed by moon July 2, 1896. I

The type-writing machine is provided with the usual frame A, supporting a basket B, in which are mounted to-swing the type-bars C, carrying the type Oand-actuated from the keys D when the latter are pressed, the several keys swinging-to a common center on the impression-roller E. Each key or key-leverD is a bell-crank the short arm of which is forked 50 at its upper end and loosely embraces a slidthe type 0 at the time the type-bar swings ing rack, Fig. 6, the latter being in mesh with teeth formed upon the type-bar hub, so that movement of the key-lever is communicated through the rack to the type-bar, thisconstruction being specifically claimed in my said original application, No. 597,828.

In front of the impression-roller E at the common center for the type-bars C is arranged an inking device designated generally as F and provided with a fountain G, having a downward projection G, covered at the front with a pad G receiving its supply of ink from a vat contained in the fountain G. The pad G is adapted to be struck by the face of upward and immediately before the impression is made on the paper held over the impression-roller E. The-force of the type striking the pad causes the latter to swing out of the path of the type to permit the latter to proceed on its inward movement and make "an'impression in the usual manner, it being understood, however, that the type has received suflicient ink from the pad upon striking it to make a properimpression.

The fountain G is secured on one end of a shaft H, mounted to turn in a suitable bearing Z, adjustably held in a bracket 1, secured to the basket B or the frame A, if desired. On the outer end of the shaft H is secured a disk J, formed in its periphery with a notch J, normally engaged by a projection or lug K, held on the free end of a spring K secured to a bracket K, attached to the basket B. On the face of the diskJ is secured apin J engaged by the free end of a spring L, A likewise attached to the bracket K, the spring serving to turn the disk J and throw the said disk J and the shaft H to swing the casing G in the direction of the arrow a after the lug K is disengaged from the notch J by the turning of the disk J, caused by theforce of the blow given by the typeO to the pad-G and its arm G. Thus when the type strikes the pad G the force is'sufficient to start the 5 fountain in the direction of the arrow a, so as to dislodge the lug K from the notch J, and then the spring L Suddenly turns the disk, and consequently the casing, to move the pad completely out of the path of the rec type C, and the latter now proceeds to make an impression on the paper held on the impression -roller E. hen the type-bar C swings downward and returns to its normal position on the release of the key D, then the fountain G is swung back to its normal position to compress the springL and to again engage the log K with the notch J. This movement is controlled by the spacing device, and for this purpose the disk J is provided with a pin J adapted to be engaged by the arm N of a bell-crank lever N, fulcrumed on a bracket Nisecured to the basket B. A spring N presses the arm N and swings the latter rearwardly to engage the pin J and to turn the disk J in the inverse direction of the arrow a, until the lug K engages the notch J and the free end of the spring L is compressed. The other arm of the bell-crank lever N is connected loosely by a link 0 with a lever P, fulcrnmed on the frameA and connected with an arm Q, projecting from a rock-shaft Q, actuated from the keys D and connected with the spacing device to operate the latter, as fully described in the application above referred to. When the key D is pressed, the arm Q, of the rock-shaftQ causes a swinging of the lever Pin the direction of the arrowb, so that the link 0 pulls on the bell-crank lever N to swing the same forward away from the pin J. As the type-bar O is now on its upward swinging motion, the type finally strikes the pad, takes ink, and causes a swinging of the fountain in the direction of the arrow a, as previously explained, the disk J being free to turn in the direction of the arrow Ct as the arm N is away from the pin J Fig. 3. As soon as the key D is released then the bell-crank lever N is free to swing backward by the action of the spring N which is sufficiently strong to cause the disk J to turn and compress the spring L to engage the lug K" with the notch J, Fig. 2.

It will be seen that by the arrangement described the type of each type-bar is properly inked when nearing the point of impression and the inking device swings out of the path of the type to permit the latter to proceed to the point of impression. It is evident that as the fountain swings upward and rearward away from the type after the latter has received the ink the pad does not rub on the type, and consequently the latter remains properly inked and does not get clogged or filled with ink, which would be the case if the pad should rub over the type or the latter over the pad.

It will be perceived that I have combined a series of type-bars, a series of key-levers, a platen, an inking mechanism arranged near the platen and normally held in the path of the types by means of a releasable lock, means for moving the said inking mechanism out of contact with the types while they are making their printing strokes and for hold-- ing it out of contact while the types are makmg their impressions, and means controlled by the key-levers through the universal bar for returning said inking mechanism to normal position independently of said type-bars.

The impression-roller E (shown in detail in Figs. 4 and 5) is provided with a shell E, of soft rubber or other suitable elastic material, and with an inner tube E to form a space with the said shell, the space being filled with a liquid or gaseous fluid E It is evident that the fluid gives an elastic resistance to the shell E to insure a proper impression when the type C strikes the paper on the impression-roller E.

It will be seen that an impression-roller constructed as described is especially valuable and serviceable when used on a typewriting machine having an inking device, as above set forth, inasmuch as the force of the type-bar is somewhat diminished by the type first engaging the ink-pad and starting the fountain on its swinging movement in the manner described. The clicking sound produced on the ordinary type-writing machine by the type striking against the hard impression-roller is completely avoided by the use of an impression-roller, as above described.

Having described my invention, I claim- 1. A type-writing machine provided with an inking device, comprising apivoted fountain having an inking-pad, a spring tending to move said fountain away from the path of the types, and a releasable locking device for locking the fountain against the action of the spring and holding it in the path of the typebars, whereby when the locking device is released by the impact of the type-bars against the fountain, the fountain will be moved out of the path of the type-bars, substantially as described.
